DESCRIPTION

Draws a wobbling blob, making use of alpha blending, fog, textures, and
lighting, plus a ‘‘frames per second’’ meter so that you can tell how
fast your graphics card is... Requires OpenGL.

OPTIONS

-visualvisual
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
visual.
-window Draw on a newly-created window. This is the default.
-root Draw on the root window. -wire Render in wireframe instead of
solid.
-delaynumber
Per-frame delay, in microseconds. Default: 10000 (0.01
seconds.).
-fog|-no-fog
Whether to enable fog.
-walls|-no-walls
Add walls for blob to hit.
-colour|-no-colour
Draw coloured blob. If also textured, the texture will have
color mixed in.
-texture|-no-texture
Whether to wrap a texture image on the blob.
-offset_texture|-no-offset_texture
Whether to ofset the texture calculations to only use a region
of the image
under the blob. This works well with a semi-transparent blob.
-blend|-no-blend
Whether to draw a transparent blob. (see also offset_texture
above)
-antialias|-no-antialias
Whether to antialias lines.
-resolutionnumber
Resolution of the tessellation used to calculate and draw the
blob. Larger
numbers give a smoother blob but increase calculation times
exponentially.
-bumpsnumber
Number of bumps used to distort the blob.
-hold-timenumber
Time until loading a new image.
-fade-timenumber
Time taken to transition between images.
-zoomnumber
Size multiplier for blob.
-fps Display the current frame rate, CPU load, and polygon count.
